Also this may sound cruel, but when they were kittens, they were so tiny I was afraid I would roll over and kill them in my sleep that we made them sleep in a large plastic tote, with a grate over it. Then in their individual cat boxes.

We only had 1 bedroom in a shared house, so this worked ok for a little while, but eventually i just ended up feeling so bad I left them out to roam during the night...they destroyed my blinds....
